Abstract

ADMA-OPCO has over 1600Km of Subsea pipelines (Transmission & flow lines) and these lines are exposed to corrosion in subsea environment whereas some of these are aging assets (+35yrs).

In the event of subsea pipeline oil leak due to corrosion drive defects or damages, the old method of pipeline repair was Hyperbaric welding, which took a minimum of 2~3 months mobilization to site to repair the damage.

Integrity Division/Subsea Team has deployed innovative and effective new Subsea repair techniques that rapidly respond to subsea oil leaks and reduce the exposure of the pipeline leaking and ensure quick return of pipeline back to service within days.

The new repair techniques have been discovered to have significant HSE (environmental protection) benefits and cost advantages.
